「I came back」は FontVibe AI で作成した3D 太字の文字エフェクトです。深く押し出された極太のブロック体大文字。一文字ずつ艶のあるキャンディカラーで、上からの光がハイライトを丸い角に走らせ、床に色の映り込みが広がります。

Massive chunky 3D block letters with heavyweight extruded presence — thick uniform extrusion depth of 50-60% of letter height. Front face finished in ultra-glossy lacquer, catching directional key light with natural specular reflections that graduate from bright highlight to deep saturated color — the surface quality of hard candy coating or high-gloss toy paint. Side extrusion planes in a noticeably darker shade of the same hue, creating crisp face-to-depth contrast that reads immediately as three-dimensional volume. Adjacent letters each carry a different vivid saturated color, maximizing chromatic contrast across the word — no two adjacent letters share the same hue family. Hard sharp corner edges where face meets extrusion, no beveling. Long dramatic cast shadows at consistent 45-degree angle, shadow depth approximately 40-50% of letter height. Strong directional key light from upper left. Bold, high-contrast, maximum visual impact. A gritty urban nighttime street scene — dark weathered brick wall in the background with faint city ambient glow, wet asphalt below catching neon color reflections, dim street lamp from upper-left casting dramatic directional light. "I came back" tilted at 12 degrees diagonal, ascending from lower-left to upper-right — "I came" on the first line, "back" larger and dominant on the second line below-right. Letters at approximately 60% of frame width — off-center, kinetic upper-right composition. I electric yellow, c hot orange, a cherry red, m electric blue, e lime green, b electric yellow, a hot orange, c cherry red, k electric blue — ultra-glossy candy lacquer catching the street lamp light naturally, dark extrusion sides, dramatic long cast shadows stretching lower-left on the wet ground. Dynamic street art energy — maximum visual impact. 16:9 horizontal format.
